Thanks very much for sharing your experience. It is very encouraging! It should help a lot of people in the same boat. You are also lucky in that you were able to find the old Family Household registration form. I tried and wasn't able to locate the original record at the local police station so far (maybe because I don't have a friend working there to help me :-) Anyway, I am doing my best to get other evidence. Will report back here if I am successful. Wish me luck!
